HAND PEGGING- MACHINE.

Specification forming part of Letters Patent N0. 4 [,884. a d March 8, 1 64-- To all whom it may concern:

,Be it known thatwe, G. H. BINGERand W. E. FIsoHER, bothresidents in Boston, in the countyof Sufl'olk and State of Massachusetts, have invented certain new anduseful Improvements in Hand Pegging-Machines; and we do hereby declare that the following, taken in connection with thedrawings which accompany and form part of this specification, isa description of our invention suflicient to enablethose skilled in the art to practice it.

Our invention relates to mechanism,lsubstant-ially like that described, which controls, under blows from ahar'nmer, the operations of such an implement.

The machine which embodies our invention is particularly adapted and designed for use with lasting machines, -whereit is employed to peg down the vamp to the in ner sole for the 'usual temporary purpose. Aslasting-machines use metallic. slides to fold the vamp over upon the inner sole, and to draw ittight upon the last, the trouble exerienced in inserting the lasting-pegs into ,sfuch parts of the vamp as are left exposed by fifthe slides is that the slides are apt to be struck ,by the hand-hammer employed, and thus become bent or broken. By the employment of our;inventi0n this trouble is avoided,'as.the action of the hammer is remote from the slides and the pegging operation is performed much more quickly that it canbe done by hand. It is not pretended that pegs willhold as well in holes formed by a squareended instrumerit-such as we employ-as they will in holes formed by a pointed awl; but it is found inpractice that for the purposes of lasting it answers every purpose to use a squareended implement in the formation of the peg-hole Similar letters refer to similar parts in all the figures of the drawings, which we'will now proceed to describe, so that those skilled in the art may be enabled to practibe our invention. v k

Figure 1 shows our machine with the awl and driver a in such a position that the pegwood is prevented thereby from being forced forward over the peg-tube, a being in readiness to be driven through the peg-tube and into the leather toform a hole for the reception of the'peg, which is done when the parts assume the position shown in Fig. 2. Fig. 3 shows a as in position above'the top of the peg which has been split by the knife i from the peg-wood, and is forced forward over the peg-tube, in readiness to be driven downward into the leather, assuming the position shown in Fig. 4.

' As is usual in most hand-peg'gersfl; ours is provided with a plunger, 0, which is driven dle to be grasped by the operative, and which terminates in a small end, so that the instrument can be worked near the edges of the lasting-machine slides and in holes and cuts therein. A. slide for. the reception of pegwood is fixed to the lower part of the instrument, and the peg-wood is fed forward to "the peg-tube in a common way by the piece 9,

actuated by an elasticcord or other suitable spring- The plunger 0 carries the knife 2', as shown, by which the pegs are split off from the peg-wood h. The, upper part' of f has a groove formed therein, in which and through v the mortise formed in the upper part of c a slide, j, of the peculiar form shown, can be made to move horizontally. The mortise in e is also made ofapeculiar form, as shown. The U-formed piecek is pivoted to theslidej at l, and is held by the spring m in the position shown in Fig. 2, when uncontrolled by other forces. The function of k is toact at one time as a stop to prevent such a rise of 0 as would admit the peg-wood to pass beneath a, so as to be over the peg-tube, and so as to act also at the same time to returnthe slideto a position from which it is forced by contact of inclined surfaces made on the slide and in the plunger.

Further explanation of construction willbc best understood by referring to the operation of the machine, commencing with the parts in the position shown in Fig. 1, where it will I be seen that expansion of spring d, and consequent movement of c to its highest place, is

arrows in Figs. 1 and 2, and to the place there shown.

Percussion upon 0 will now move it down, puncturing a hole in the leather and splitting a peg from the peg-wood by action of i, and the extent of the downward motion of c is checked by the contact of the surfaces q and 'r with s and t.

After the percussion cis forced upward by springs e and d, bringing the inclines o and 12 together, the effect of which is to slide j into the position and in the direction shown by arrows in. Figs. 3 and 4; but now this upward movement of c is not checked by the catching of kin notches n, and c obtains its highest po-' sition, because j and k keep the position shown in Fig. 2, where k is not liable to be caught in the notches, inasmuch as the inclines 0 and 1) do not act to move j till the notches n have passed beyond the ends of It, so that its engagement in them is then impossible.

Now, inspection of Fig. 3 will show that'a blow upon 0 will notforce a farther down than i to the end of the peg-tube, because the position of j is such as to bring the surfaces r and 3 together, as seen in Fig. 4.

. Now, when a is relieved from percussion, it

will be forced upward by the action of springs d and e; but it cannot move upward farther than shown in Fig. 1, because in its upward movement its notches n engage 7c, and make It and j assume the position shown in Fig. 1. The slide j cannot be forced upward, because it is checked by the pins u, and further upward vibration of k is checked by pin 1;,- hence the force of spring dis exerted to move j in the direction shown by the arrows seen in Figs. 1 and 2.

From the foregoing it will be seen that one blow from ahammer makes a hole for the in sertion of a peg, and cuts a peg from the pegwood, in readiness for the next blow, which forces the peg into the leather, it being understood that between the blows the peg previously split ofl' from the peg-wood is brought over the peg-tube, so as to be subject to the action of a in its descent.

We claim- A mechanism, substantially as herein de' scribed, for alternately operating by percussion to give long and short strokes to the in strumenta.
